After obtaining the first target sub-illuminance L of the first light source a in the triangular ABD, the second target sub-illuminance L of the triangular AED, and the third target sub-illuminance L of the triangular ACD, the output sub-illuminances L of the light sources corresponding to the vertices in the triangular ABD, triangular AED, and triangular ACD are determined according to the determination method of the output illuminance of each light source by the three-color lamp (a specific output illuminance determination method, please refer to the embodiment of the three-color lamp, i.e., the output illuminance determination method in the embodiment corresponding to fig. 2, which is not described herein again), and the first output sub-illuminance L of the first light source a in the triangular ABD is obtaineda1A second output sub-illuminance L of the second light source Bb1And a third output sub-illuminance L of a fourth light source Dd1Fourth output sub-illuminance L of first light Source A in triangular AEDa2A fifth output sub-illuminance L of a fifth light source Ee1Sixth output sub-illuminance L of fourth light source Dd2Seventh output sub-illuminance L of first light source A in triangular ACDa3And the eighth output sub-illuminance L of the third light source Cc1Ninth output sub-illuminance L of fourth light source Dd3. Then, the sum of all the output sub-illuminances of the same light source is used as the output illuminance L of the corresponding light source, i.e. the output illuminance L of the first light source Aa= first output sub-illuminance La1+ fourth output sub-illuminance La2+ seventh output sub-illuminance La3Output illuminance L of the second light source Bb= second output sub-illuminance Lb1Output illuminance L of the third light source Cc= eighth output sub-illuminance Lc1Output illuminance L of fourth light source Dd= third output sub illuminance Ld1+ sixth output sub-illuminance Ld2+ ninth output sub-illuminance Ld3。
